0-60 in 4.6 seconds
would you say (as far an engine temp) the first runs the car is faster than the latter ones, because the eingne temp?
It seems like whenver i run with ECT on i get better AVERAGE times. but in Drive the range of times is wider. I can get a lower time than with ECT on, but also my best 0-60 times have been with the car just in Drive (no ECT).
Bear in mind that accelerometer based measuring devices (what I assume everyone is using for their #s here) are generally accurate to 0.1 seconds... so any variance in that range or less is already inherent to the device, even when used -exactly- perfectly.
Typically yes a cooler engine (at operating temp, since you obviously don't want to push it when entirely cold) will produce the best results... but each car will vary somewhat in how sensitive it is to heat soak.
My last car, which I took to the 1/4 mile track a number of times, would usually be able to put down good solid numbers for at least 4-5 runs before you'd notice any heatsoak at all (and these were 1/4 mile runs where you're keeping it floored 12+ seconds at a time to over 100, not just 0-60 runs).
I haven't done any repeat-run testing with my IS like that though to know when engine heat will begin impacting results... with virtually no mods making significant changes to vehicle power I doubt I'll be visiting the 1/4 mile track much with this car (compared to the previous car where I doubled stock hp over various mod stages)

Ah sorry, I've owned a bunch really, but the most recent one was a '95 Impala SS... bit north of 500 hp naturally aspirated. Displacement was 6.3 L by the end though, and pushrod technology, so a bit tough to compare as far as susceptibility to heat soak. Had a couple supras as well, among others, but again, pretty different engine.

Dont hate the Juice, hate the Vector
Juice14, good work. You are very entertaining in our forum. I enjoy reading most of your posts.
What juice14 said above is correct............. In this run it is highly likely he got 4.5x sec, not 4.6.
And juice, I see in this video you ran it with 3 quarter tank full of gas. That's not good. That is guaranteed 110% to slow your car down. Do the launch at quarter tank of gas or 1/8 tank. Or at empty tank. You can get better time than 4.5 sec. 3 quarter tank...... you are asking for trouble.

do you think it was a Vector FX glitch?

Nice run juice!
What was the temperature outside when you did this run? Was it about the same temp as your previous runs? (35~ 40F?)
I see you did it with quarter tank of gas too. Great to see the improvement man... Who knows, maybe you actually got 4.45 sec.
I kind of doubt it it's the Vector FX glitch as that 0-60 run is very possible.I gotta start doing some testing on my car too soon. You are representing the IS350 performance really well. That's great.

Dude you have a factory freak..if my IS ran this quickly I'd be flooring it all over the place too. I'm limited to just flooring it onto freeways and taking hard corners w/ high rpms and low gear. PAINT YOUR ROOF BLACK DAMNIT.

It actually wasnt that cold. it was only about 50 degrees. However it was dry and crisp. Another thing i did different, was drive the tires for a lil bit and warm them up. all the other runs I do are, warm up the car and go to the straight and try it, It only like a mile away from here, so I think the tires never get hot. today i drove about 10 minutes running some arons and got this suprisse of 4.5 I couldnt believe it.

There is another guy (Mod) IS-F-Hope at My.is forum and he got 13.2x sec quarter mile in his stock IS350. I would imagine his 0-60 run at the time would've been spectacular also.

Actually..... as long as the car is in good condition these 0-60 numbers can be had if you know what you guys are doing. Even car mags (Road&Track and Car&Driver) both got 4.9 sec out of IS350's and they were tested in the summer when it was hot. These cars were not broken-in either. What Juice14 is representing, is very possible, and showing us what our IS350 cars can do. Keep in mind his was done in a good weather and it has gone through a break-in period. Check his mileage it's at 52xx miles. I have seen some IS350 owners that they seemed to get even better results (compare to their previous runs when theirs were new) after about 10,000 miles.

I agree.
See, I am not sure if cooler weather would be better time because then that might mean the street is colder as well. sometimes i get excited when it gets down to the 30's and try 0-60 and cant get any grip. but once the car does grip is much faster.
so i think I went at the perfect time since the sun was hitting the pavement for a couple of hours and it wasnt too cold, or too hot. also it seemed to be a very dry day, no humidity which helps a ton too.
Another factor that might have helped was the wind. maybe i had some tail wind.

Hey, quick question I thought may pertain to this thread.. Has anyone had a chance to time or run an 09' IS350? I am coming up with no answers as to why the factory 0-60 time stated is different this year, its 5.6 instead of 5.3, like 06-08 were. I wonder if the 09' is actually slower? Maybe added weight? Or maybe they tested it in the hot summer this time?? lol Weird!
